I agree with Bumblebee. I would incline to a "cellar" of salt for online trees pre 1700, or at least a teaspoon's worth.
I'd be interested to know where a dob of 1510 came from, unless it was estimated from his death.
There are 16th & 17thC rent rolls for the family line I mentioned in my previous post but even so I've traced my descent only back to c1694. ( 6xGGF, born in parish according to another record, was not in baptism register anytime around then, not surprising as he was Catholic. ) The parish register began 1679. Members of the family turn up in manorial records, Quarter-Sessions, Papists' Returns, and wills. I've eliminated some people through reading wills, sometimes making a family tree for each executor. They were all yeomen, farmers, innkeepers, craftsmen, tradespeople. I've researched other families with whom they were closely connected and read about the locality and history, in order to put my family in context.
